A sustained tonic anchors your ear while you improvise, sing, or move through a mode. Pick a root, pick a style, press play.
Root, fifth, and octave - a lush, singing bed.
When there’s no backing track, a drone quietly insists on the tonic. Every line you play lands somewhere relative to it - you hear consonance and tension the moment they happen, instead of guessing after the fact.
Put on a D drone and play D Dorian. Switch to E and play E Phrygian. The drone is the cheapest way to actually hear how each mode colors the same seven notes differently.
Singing or playing over a held tonic trains the ear - and the fingers - to resolve cleanly. It’s the oldest trick in Indian classical music for a reason: nothing sharpens pitch like a fixed reference.
Comp a ii-V-I over a drone on the I. Each chord glows differently against the fixed tonic - this is the fastest way to internalize function instead of just memorizing shapes.
Your root, style, octave, and volume persist between sessions - and the drone keeps sounding as you navigate the app, so you can pair it with any exercise.
